Thanks to Julius LaRosa for pointing us toward a performance with the Oscar Peterson Trio by Ella Fitzgerald late in her career. Peterson sits out most of the first chorus. Bassist Niels-Henning Ørsted Pedersen generates the powerful swing with Fitzgerald. Then the pianist and drummer Martin Drew join the ride. Ella is rarely singled out for her low-register chops, but take notice of her deep range in the third chorus.
It do mean a thing if it has got that swing
Have a good weekend.
